3. A Finmeccanica Company 4ie-idxxxxxx-x 3 Reference scenario A horizontal communication model is required Service and network resource management must be upgraded for wireless systems to operate in a composite radio infrastructure S E C U R I T Y ?

4. A Finmeccanica Company 4ie-idxxxxxx-x 4 Main goals Design a proof of concept of an integrated seamless network which ensures: global personal connectivity access to broadband wireless multimedia communications and services to anyone, anywhere, anytime Develop specific enabling technology for: enhancing the user friendliness of the communications equipment aiding the integration of converging infrastructure technologies onto a common platform accessing customised services over networks operating with different radio standards across different frequency bands Provide SECURE wireless/core network integration through: an adequate middleware layer to efficiently access resources available in the wired part a GRID-enabled infrastructure to manage computing and storage resources

5. A Finmeccanica Company 4ie-idxxxxxx-x 5 A new vision of GRID Recently Grid technologies is seen as a more “rational” management of distributed resources in terms of: Load balancing QoS management Secure access As the amount of potential users is really enormous, the accumulated data processing and storage requirements are at least comparable to those of typical Grid applications Our vision is: to disclose Grid potentialities to a wider audience, which is mainly constituted of users with every day problems and requirements who want to access real-time and interactive context-aware applications

6. A Finmeccanica Company 4ie-idxxxxxx-x 6 Wireless and GRID: an integrated approach To provide value added multimedia services to mobile users roaming in a multi-technology wireless environment To promote GRID also in non-scientific applications, involving mobile users, residential users, SMEs, research centres and industries To reverse the logic to adopt GRID for single, specialized high-demanding applications to allow many “simple” users to transparently access distributed computing and storage resources anyhow, anywhere and anytime S E C U R I T Y ?

8. A Finmeccanica Company 4ie-idxxxxxx-x 8 Innovative aspects 1/4 to take care of all the requests to select which are the more convenient servers to identify the more convenient access technology to deal with the QoS requirements to distribute the requests on all the available servers in general how to optimise the use of the available resources.  To manage user and service mobility through a GRID-enabled middleware. While the user is roaming from one place to another, the system will decide how:

9. A Finmeccanica Company 4ie-idxxxxxx-x 9  To investigate adequate mechanisms able to guarantee both users and service providers that only authorized actions are executed. More specifically:  identifying the security requirements of a user  adjusting and negotiating the security based on the user requirements and capabilities at a given time  developing a unified distributed security architecture managing all security aspects:  autentication  data protection  infrastructure protection  terminal protection Innovative aspects 2/4

10. A Finmeccanica Company 4ie-idxxxxxx-x 10  To analyse how the GRID may influence the communication infrastructure:  which mechanisms are needed to decide the optimal way to deliver a service considering the status of network and routers?  how to develop coordination strategies among routers (eventually through mobile code) to manage a traffic flow differently from others?  how to deal with QoS guarantees?  how to cope with mobile users?  how to optimise the use of core network and wireless resources?  hardware requirements for next generation mobile terminals Innovative aspects 3/4

11. A Finmeccanica Company 4ie-idxxxxxx-x 11  To experiment new value added services which exploit:  User mobility  Service adaptation and reconfiguration  Service scalability and personalization  Transparent access to distributed resources  Real-time scalable multimedia content creation and streaming  Multimedia-streaming services over the GRID network  Seamless and pervasive security provision Innovative aspects 4/4

12. A Finmeccanica Company 4ie-idxxxxxx-x 12 …Converging where? Transparency of the service Security requirements Security MUST benefit/support: flexibility in delivering more advanced services programmability at the network level dynamic reconfigurability distributed intelligence autonomy delegation Mobility of users Accessign high computational and distributed resources creation of a suitable middleware

14. A Finmeccanica Company 4ie-idxxxxxx-x 14 Main Aims Conclusions User-centric approach focusing on their individual needs GRID extensions with a unified security architecture Support of mobile users by developing an hybrid infrastructure with growing wireless components Definition of explicit end user admission control methods to support quality of service management and control Support roaming users with service portability, session mobility and service scalability Ensure programmability at the network level, distributing intelligence in the whole system Allow citizens to easily access more advanced services, with guaranteed QoS Protect the interactions against intrusion, manipulation and disruption Manage all the communications among the processing nodes to ensure QoS …SECURELY LOOK FORWARD

15. A Finmeccanica Company 4ie-idxxxxxx-x 15 Conclusions and Comments We feel confortable for the value of the security aspects in our framework Are there other security aspects we did not envisage? We would like to integrate other security aspects Which are the important ones still not included? We would like to focus on specific issues for a testbed Which ones are the best?

16. A Finmeccanica Company 4ie-idxxxxxx-x 16 Question Should we look forward to Wireless SECURE extensions to mobile enabled applications of the Future EU GRID Infrastructure?
